Air pressure crankcase TC96
I have a bone stock 2010 ultra glide with 30k.
When twisting, removing oil dipstick I get a prolonged rush of air emitting from case.
Even a 10 second run of engine will produce this air pressure.
No oil wetting around air filter.
No leaks anywhere.
Engine runs great.
Lessened oil level to halfway below full on stick.
I hear conflicting advice, even from dealer service departments annoying.
Perhaps some in-depth reputable knowledge on our forum.
Dont want to risk any damage in this state.
Thanks all.

Pull the A/C cover and pull the tubes off the breather bolts, put your finger over the holes with the engine running, see if you can feel pulsing, you can even pull the breather bolts and check.
After running with the tubes and/or bolts removed, see if it still has pressure when removing the dipstick.
If it does, need to go into the rocker boxes and dig into the breathers.

Kinda seemed like he was in a rush
But do we need another 20 pages ?
I am shocked dan didn't bite his head off. Maybe turned over new leaf or holiday spirits
